Bug 30532 – app-sci/yacas could have optional gmp support

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Pablo De Nápoli 2003-10-06 19:42:45 UTC]

Yacas could have optional support. I suggest adding an USE 
parameter gmp (and build it with configure --with-numlib=gmp if
this parameter is selected)

Reproducible: Always
Steps to Reproduce:
1.
2.
3.

[Comment 1 Pablo De Nápoli 2003-10-10 10:26:23 UTC]

I'm sending to you an ebuild that fix this bug for yacas 1.0.55
(for yacas 1.0.54 this not work, because fstab function is not declared
in gmpnumbers.h and compilation fails, but this could be easily be fixed
patching this file, I'm not sure about the way of doing this in the
ebuild script. Is there some utility for this or I just use patch/diff?
This upstream bug is already fixed in yacas 1.0.55)

used "USE" parameters should be in IUSE. Please attach it as text/plain instead
of pasting.

[Comment 3 Pablo De Nápoli 2003-11-09 15:14:53 UTC]

Created attachment 20485 [details]
ebuild to fix this bug

I'm resending the ebuild according to comment #1 (with the modification
requiered: gmp is in IUSE)

[Comment 4 Pablo De Nápoli 2004-01-18 11:23:28 UTC]

gmp is much more efficient than the built-in arbitrary precision 
library

[Comment 5 Patrick Kursawe (RETIRED) 2004-04-19 09:11:59 UTC]

Compilation fails with gmp-4.1.2, though, when using a current gcc.
Investigating...

[Comment 6 Patrick Kursawe (RETIRED) 2004-04-19 10:03:16 UTC]

I hope I fixed it. Please try when .56 is available.
